The reason I knew about the movie Ratatouille is that 4 years ago my friend had a 50th birthday party at an industrial kitchen in Emeryville, next to Berkeley. It was one of those parties where the guests help prepare a gourmet meal with the help of top chefs, or actually, it's the other way around. Anyway, they told us that Disney had recently used this kitchen to shoot chefs at work so they could get the movements right for the animation for Ratatouille!
